2(xy-7)=?
When variables are connected such as xy, this means to multiply.
x=-1
y=3
Multiply the x and the y together.
-1*3=-3. Plug that into the equation.
2(-3-7)=?
Subtract the inside the parenthesis.
2(-10)=?
Multiply. Remember when multiplying a positive and a negative the answer will always be a negative.
2(-10)=-20
This means that 2(xy-7)=-20 with the x=-1 and y=3.
Hope this helps!
If not, I am sorry.
